EPC has introduced a new high-efficiency power converter designed to accelerate the adoption of 800 VDC power distribution in next-generation AI data centers.
As artificial intelligence workloads continue to expand, future data centers—often referred to as AI factories—will require megawatt-scale rack-level power delivery systems. To meet these demands, EPC has developed a compact, low-cost, 6 kW GaN-based converter that steps down 800 VDC to 12.5 VDC using an Input Series Output Parallel (ISOP) topology.
The converter delivers multiple key advantages:
- High power density: The design occupies less than 5,000 mm² of board space and measures only 8 mm in height, making it ideal for space-constrained AI server boards.
- High efficiency: By converting power close to the load, the system minimizes bussing losses and enhances overall energy efficiency.
- Simplified architecture: Moving directly from AC to 800 VDC at the rack level and then stepping down to 12.5 VDC at the board eliminates unnecessary conversion stages, improving scalability and reducing system complexity.
EPC’s GaN-based approach supports the evolution of AI data centers toward more compact, efficient, and sustainable infrastructure.
“GaN is an essential technology for the 800 VDC ecosystem,” said Alex Lidow, CEO of EPC. “Our collaboration with NVIDIA focuses on delivering compact, efficient, and cost-effective board-level power conversion to support the next generation of AI factories operating at gigawatt scale.”
The development underscores EPC’s commitment to advancing GaN technology as a cornerstone for future high-voltage, high-efficiency power architectures in AI and high-performance computing environments.
